We've seen this napari error before in brainreg: https://brainglobe.zulipchat.com/#narrow/stream/408839-dev-private/topic/.E2.9C.94.20Brainreg.20test.20failure/near/431276552

Though it was supposed to be fixed by napari/napari#6799 on napari's end, and it looks like someone in the last 3 days has commented on the PR.

Thanks @willGraham01 - I guess the fix just hasn't made it into a new napari release yet? I was getting around this locally by using pip install lxml_html_clean in my environment.

👍 Looks good! I'll merge this and open a PR to deal with the failing tests, and #32.
